The 16 Channel 5V Relay Module with Optocoupler is an industrial-grade interface board designed to let microcontrollers, Arduino boards, and IoT controllers switch heavy AC or DC loads. 5V DC logic level · Up to 10A at 250V AC or 10A at 30V DC per channel.
The 16 Channel 5V Relay Module with Optocoupler is an industrial-grade interface board designed to let microcontrollers, Arduino boards, and IoT controllers switch heavy AC or DC loads. Each of the 16 onboard relays is equipped with high-current switching contacts capable of handling up to 10A at 250V AC or 30V DC.
Featuring built-in optocoupler isolation, this module protects sensitive control circuitry from voltage spikes, electrical noise, and back-EMF. It includes trigger selection jumpers allowing high-level or low-level triggering, optical isolation for each channel, and working indicator LEDs to easily monitor relay status during prototyping and deployment.
